    htu21: allow configuration via hints on FDT-based systems
    
    On-board devices should be configured via the FDT and overlays.
    Hints are primarily useful for external and temporarily attached devices.
    Adding hints is much easier and faster than writing and compiling
    an overlay.
    
    (cherry picked from commit a75159eabc90dc35af68c92f7d5eb72e087f6131)
